I keep reading about two extra SATA ports on a Mac Pro's logic board, behind the optical drive(s).

How are folks accessing those? Are there instructions posted somewhere for reference?

What do you want to use them for? If you want to take those ports external and add more storage I would advise you just get an inexpensive host card. A 2 port card costs a little over $50 and is worth it for the features like hotplugging, hotswap and port multiplier. To mount a drive to one of the internal ports you have to reboot each time. Maybe not a terrible inconvenience, but not all that great for an external purpose either.

Those 2 ports appear to be intended to support a pair of optical drives internally - if one desires to use SATA DVD burners. I have a SATA DVD drive attached to one on my MacPro and even the eject buttons work for it.

I would not advise anyone add more than the 4 hard drives that Apple engineered for inside a MacPro. Temperature variations on drives - even in the 4 slots provided - are not optimum. Adding more than that is a good way to cook components.
